It's not a great picture, but is it a Thomastik Superflexible? I don't have one sitting around to check the pegend color, but the ballend color looks right or close. The little felt washer, however, suggests Pirastro.

Man, it must be nice to like your g-string that much. No temptation to try something different. I envy you.

I'm partial to the Pirastro Obligato set - that's right, the whole set! Beautifull gutty sound, lotsa highs and lows. After I installed the full set, a cellist at my job thought I'd bought an Old Italian instrument because of the rich, suave sound!

I totally forgot about this thread.. Yes, it seems from the string ID page that my broken G-string indeed was a Chromcor. And yes, I was very happy with it. Since I was in a hurry, I had to buy a Thomastik Spirocore to replace it - the new string was much weaker in its sound (less volume, less fundamental) and slighly higher in tension.

Then my D broke aswell. Since I did not want that crappy experience with another Spirocore, I bought a full set of Garbos. I just put them on the bass, and to be honest, I still miss that Chromcor G-string. I'll give the Garbos a couple of weeks, but if the sound is not what I'm looking for, then perhaps I'll try a set of Chromcores?
